Densities, viscosities, refractive indices, and surface tensions of a ternary system (1,3-dioxolane + 2-propanol + 2,2,4-trimethylpentane) at T= 298.15 K and two binary systems (1,3-dioxolane + 2-propanol and 1,3-dioxolane + 2,2,4-trimethylpentane) at T= (288.15, 298.15, and 308.15) K were measured over the extensive composition range at atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Viscosities were measured with an automatic microviscometer based on the rolling-ball principle. Refractive indices were measured using a digital Abbe-type refractometer. Surface tensions were determined by the Wilhelmy-plate method. The excess molar volumes V(E) were calculated from the experimental density data. The results are discussed in terms of molecular interactions.
